Abstract This work surveys the structural and physical properties of layered hexagonal (A3+M3+O3)(M2+O) and (A3+M3+O3)2(M2+O) phases where A3+ = In, Lu, Y, Yb, M3+ = Fe, Ga and M2+ = Cu, Mg, Zn. This family of compounds is of recent interest because of the trigonal bipyramid coordination that is rarely observed in transition metal oxides. The lattice parameters for a number of the (A3+M3+O3)(M2+O) and (A3+M3+O3)2(M2+O) compositions are provided herein, in addition to the bond lengths and atomic positions of selected compositions. The triangular geometry of the cations in the trigonal bipyramidal layers adds a component of frustration into the system, specifically with the magnetic properties. The work summarized in this review has used cation substitutions into the trigonal bipyramidal site of YbFe2O4-type compounds to further understand how the rare crystallographic coordination dictates the observed physical properties.

YbFe2O4-和Yb2Fe3O7-型层状氧化物的结构-性能关系：鸟瞰图

摘要 这项工作调查了层状六方 (A3+M3+O3)(M2+O) 和 (A3+M3+O3)2(M2+O) 相的结构和物理性质，其中 A3+ = In、Lu、Y、Yb、 M3+ = Fe、Ga 和 M2+ = Cu、Mg、Zn。由于在过渡金属氧化物中很少观察到三角双锥配位，这一系列化合物最近引起了人们的兴趣。除了所选的键长和原子位置外，本文还提供了许多 (A3+M3+O3)(M2+O) 和 (A3+M3+O3)2(M2+O) 组合物的晶格参数。组成。三角双锥层中阳离子的三角形几何形状为系统增加了挫败感，特别是磁性。
